EXPERIMENTS WITH FLAX

Experiments with flax at the Dickinson Experiment Station in 1955 included varietal field plot trials of twelve varieties and nursery trials of twelve varieties and selections.

FLAX VARIETAL TRIALS

Yields were fairly good in this years flax variety trial with Dakota, Linda, Marine and Bison all yielding seven or more bushels per acre. Dry weather in July reduced the potential flax yield and was favorable for weed growth which also aided in reducing the final crop yield.

FLAX NURSERY TRIALS

Yields in the weed free nursery trials were more than double those from the field plot trials. CrystalxRedson, C.I. 1608, was high yielding entry in this trial with an average of 16.7 bushels per acre. Raja was the lowest yielder with an average yield of 11.3 bushels per acre.

Data from the flax varietal trials are given in tables 13 and 14. Data from the 1955 Uniform Flax Nursery are summarized in table 15.
